PROBLEM TO BE SOLVED: To provide an electromagnetic shield device simplified in structure yet capable of highly reliable electromagnetic interference inhibition. SOLUTION: The device has a signal processing circuit 11 having inverters 13, 13 for generating signals reversed in phase from normal signals for display, a transmission channel 14 wherein lines for transmitting normal signals and reversed signals outputted by the signal processing circuit 11 are located adjacent to each other, and a liquid crystal display 15 into which the normal signals and reversed signals transmitted by the transmission channel 14 are inputted. The electromagnetic waves from the normal signal lines and those from the reversed signal lines are offset in the space accommodating the transmission channel 14, and this protects an interference-susceptible section 16 positioned near the transmission channel 14 from electromagnetic interference.
